$52,686

Medicare paid this office $52,686 for 240 people.

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Who their Medicare patients are

240 Original Medicare patients in 2024. Average age 77 · Under 65 6% · 85 and older 28% · Women 50% · Also on Medicaid 32% · Health risk score 2.47. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Chronic kidney disease 63% · Coronary heart disease 53% · Diabetes 46% · Heart failure 46% · Depression 36% · Atrial fibrillation 35% · COPD 31% · Dementia 28% · Cancer 27% · Stroke 23%.

The office billed $226,648, Medicare allowed $68,271 and paid $52,686; for 514 services of 10 kinds.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

$2,765 in 2022

Medicaid paid $2,765 for 80 billed services this clinician did in 2022, up to 15 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

$11,011

Pharmacies billed $11,011 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 9% of their Part D prescriptions (14 of 163) in 2024. A higher opioid share than 9 in 10 peers; the typical internal medicine clinician is at 1%.

147 generic and fewer than 11 brand-name prescriptions · $11,011 in drug cost · 22 antibiotic prescriptions to 18 people.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

$22 in 2019

A payment is not proof that care is biased.
